I thought this article was a brilliant workaround and wanted to share. It was original posted over at:
Let¢s say you have a column named “TicketNumber” of number type in your list. By default SharePoint formats it to show with commas. If your requirement is not to show those comma¢s then here is a workaround.
Create another column of “Calculated” column type and set the formula as follows:
=TEXT(Original_Number_Column_Name,¢0¢³)
Ex: =TEXT([TicketNumber],¢0¢³)
And then use the calculated column in place of your original column for display purposes.
